Abstract: The surface of a magnetic disk (23) is divided into servo sectors (S1) and data sectors (S2). A selectively positionable magnetic head (24) effects, in predetermined time intervals controlled by clock signals of a clock sensor (26), the transfer of servo and data signals. The servo signals sensed in the servo sectors are used for the track following control of the magnetic head.
